There should be 2 wires coming from under the intake, This is the knock sensor "jumper" harness on Gen III engines, If the knock sensors are on the side of the block....You have a Gen IV engine....& the harness you have wont work anyway.

05 & 06 LS2's are the exception to this rule, They are Gen IV but still use a 24X crank reluctor.....So you can run Gen III electronics on this engine. ALL other Gen IV's use a 58X crank reluctor.
